@hazardwarning It's out of fashion with most historians these days, but I still think the best one-volume resource for a broad overview is The Rise and Fall of the Third Reich by William Shirer. It's not perfect, but it is exhaustive in its scope. Follow that with more recent and specialized reading, such as the book on IBM that Konrad mentioned. (Edited to remove the recommendation of the Goldhagen book, as I haven't read it in a while and it has become extremely controversial.)
The Israel-Palestine thing is vexing. For my own part, I don't think anyone can look at it and conclude that the blame lies all with one side. It's a cursed history. And in truth, Israeli settlements on the West Bank don't help. Neither do Hamas rocket attacks, nor the Israeli blockade of Gaza.
I look at it and tend to side with ordinary people who just want to be left alone. I'm a pragmatist; neither side is going anywhere, so both sides need to ratchet down the violence. I'm on the side of Palestinians who face Israeli destruction of their homes, and on the side of Israelis who get blown to bits when a suicide bomber blows up a bus in Tel Aviv. May they all someday decide they love their kids more than they hate each other.
